That's an old kernel. Can you reproduce on a current TOT kernel?
It's entirely possible that this problem has been fixed as we
definitely mae some changes to the mount error handling path since
3.2....

Can you narrow this down from "takes several days" to the simplest
possible reproducer? It happened due to IO errors during mount, so
maybe you can did that part out of your script and give us a test
case that reproduces on the first mount?
